This project fits more for custom made battery casing that can have more space to hide things inside. This switch with few alterations can be used for any other project as well but is designed based on e-bike needs! This project use a clever functionality of.... -
The circuit described here uses ultrasonic oscillations and operates based on the propagation velocity of these oscillations in the air. Thus, we can easily determine the distance of two points if the time within which the wave travels this distance is.... -
Sometimes the precious metals are hidden too deep and are not detected except with complicated devices. In many cases, however, small pieces of precious metal buried near the surface can be detected by relatively simple means. Everyone is very attractive to.... -
Many times for various reasons we forget or can not water the plants that we have in our homes. And many humidity sensors units just notify us with a beeping sound or with a flashing light, that the pot needs watering. But what if we are away from home? This.... -
The principle behind a metal detector is really very simple. Proof of this is the circuit that follows, in which it proves that the construction of a metal detector can be done in the minute, with few components that we find very easily everywhere. With the.... -
The sub-harmonic bass generator is a sound producing unit for guitars. The sound it produces looks very much like that of the bass guitar. The octave generator is sometimes quite unusual since it does not produce any of the usual ways of coloring the sound,.... -
In the past the sounding (sea bottom measurement) was done with the "bullet", that is, with a heavy lead object that the seamen plucked into the sea hung from a calibrated rope. As soon as the "bullet" reached the bottom, the depth appeared directly from the.... -
This Amplifier was designed to have the following specifications: Distortion less than 0.1% at full power of 100W even at 20KHz. Power has to be attributed to an extended bandwidth. The output transistors must be protected against short circuits. The power.... -
A series of LEDs serve to alert the gardener when plants need water. Using two conventional digital integrated LEDs and a series of LEDs, we make a very useful device for gardening. The device detects the amount of water in the pot and alerts the grower.....

This circuit has `suffered` a lot of modifications over its long life... Even the lettering on...
Based on the classic Baxendall tone control circuit, this provides a maximum cut and boost of...
This is a handy, easy to build general purpose 50 watt amp. The amp has an input for a radio, TV,...
This smoke detector uses a MEM 817 p-channel enhancement mode MOSFET as its buffer amplifier....
C1 = 3 750 pF 500 V silver-mica capacitor. C2= 100 pF preset capacitor (Jackson C803). C3 = 75...
This week we were in a Southern mood in anticipation of Spring Break, so we initially decided to...
This circuit is a frequency meter, low cost. It covers region 1HZ until 1MHZ. The IC1 schmitt...
ISP Programmer Please buy USB programming cables at last and start using AVR Studio, avrdude etc....
This USB car charger adapter project is a DC DC power converter that safely converts the 12V car...
The circuit shown below can be used for measuring frequency or Hz. The IC is very simple to make...
The block diagram below shows how the removable memory card or MMC card connection to other...
This article is about a simple 5 channel radio remote control circuit based on ICs TX-2B and...
This application note describes a low cost, high performance UHF short-range Radio ASK receiver...
Almost all 24V power systems in trucks, 4WDs, RVs, boats, etc, employ two series-connected 12V...
The Intan Technologies RHA2116 16-channel integrated amplifier array requires only three external...
Model aircraft pilots like to use PC-flight-simulator software to train the handling of model...
